Taxonomic Keys

"Amelanchier cusickii flowers 10 to 15 days before A. alnifolia, which suggests that these two are genetically distinct. G. N. Jones (1946) noted that A. alnifolia and {i{A. cusickii frequently grow together but that there is “no evidence of hybridization.” It should be noted that Jones discounted hybridization in the genus, even denying hybrid status to A. x neglecta." - Campbell & Doucette
